hey im have the same probs in u go into setting and performances and change the latency it shud kick in. have u tred instailing "USB Audio Driver - Combined 32/64-bit 3rd party ASIO driver by ASIO4ALL: " as well as "USB Audio/MIDI Driver - Combined 32/64-bit driver:" form http://www.behringer.com/EN/Products/BCD3000.aspx

The BCD series is also well known to be problematic for many users, especially the audio driver. It's possible that it may not be compatible with your operating system. The latest drivers can be downloaded from Behringer's website.

As above, the BCD3000 won't work with VirtualDJ LE for VMS4 unless your 20 day trial Pro is still active. v7.0.5 is also an old and out-of-date version, so you should try it with the latest Home FREE v7.4, which allows controllers to be tried out for 10 minutes at a time (Although If you own a VMS4, not sure why you would want to downgrade to a BCD3000, which is now quite old technology.)
